IMPRQVEMENT IN MOLDING- ACHINES.

Specification forming part of Letters Patent N0. 97,@@, dated November23, 1869.

To all whom it may concern.-

Be it known that I, A. S. GEAR, of New Haven, in the county 0i'y NewHaven and State of Connecticut, have invented a new Improvement in WoodMachine; and I do hereby declare the following, when taken in connectionwith the accompanying drawings and the letters of reference markedthereon, to be a full, clear, and exact description of the same, andwhich said drawings constitute part of this specication, and represent,in

Figure 1, a side view; Fig. 2, a front view; and in Fig. 3, a top view.

This invention relates to an improvement in molding-machines, the objectbeing to recess the surface of the wood to be wrought, in order to forma panel thereon, and at the same time to mold the 'edge of the recess;and the invention consists in a vertical cutter-spindle arranged in ajointed frame, and attached to the driving-shaft, with carrying-pulleysarranged at the joint, so that the cutter-spindle may have a universalmovement over the surface to be wrought, combined with a form or patternheld upon the wood to govern the form of the panel.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe the same as illustrated in the accompanyingdrawings.

A is the table, arranged upon a support, B; G, the driving-shaft,supported vertically in bearings D D, and so as to be raised up orlowered down therein by means of a lever, E, having its fulcrum at a,and held in position by a latch, b, the said latch operated by a lever,F, as seen in Fig. l, so that by taking hold of the lever E and clampingthe lever F down the latch b is withdrawn from the notch on the frameand the lever raised or depressed, as the case may be, and when at therequired elevation the latch flies back into the corresponding notch inthe frame. p

To the driving-shaft, above the table, a frame, G, is hung, whichsupports the shaft H, upon which is arranged a pulley, H', correspondingto a pulley, G', on the driving-shaft, so that a belt extending aroundthe two pulleys will cause the pulley H to revolve when thedriving-shaft is revolved.

Molding and Paneling ing its vertical position and elevation, and`revolving the same into whichever position it is turned.

The raising. or lowering of the shaft of the lever E adjusts theelevation of the cutterspindle.

The cutter-spindle, as illustrated in Fig. 4, is formed with adetachable guide, N, above the cutters n. The object of this guide is towork against the pattern and govern the line or movement of the cutter.

Wis the wood-surface which is to be wrought. It is laid upon the table,and over this the pattern P is placed, the pattern being first cut tothe. form which is desired for the edge of the recess, as seen in Fig.3. Placed on the table, the pattern and wood to be wrought are clampedby any suitable device, here represented as by clampingscrews S.

For convenience of moving the cutter-spindle frame, I x thereto handlesR R. The operator, when the machine is in motion and properly adjusted,places his hands upon the two handles and moves the cutter within thepattern, so as to cut away the surface of the wood, the patterngoverning the line of movement around the edge. -Patterns are appliedwhenever any portion of the original surface is t0 be retained. Theguide N on the cutter-spindle works against the edge of the pattern, andthe cutters are constructed to give whatever form or mold it isv desiredfor the edge. By thus governing the cutters the operator can adapt themovement of the cutter to the nature of the wood which he is cutting.If, having cut one depth, it is desired to cut still another by the samepattern-that is to say, so as to make a double sink77 in thepanel-different-sized guides N may be applied, one after the other, toaccomplish the desired result.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is

2 miss that the said spindle may be moved over the surface of the Work,as described, guided by the said pattern, substantially as and for thepurposes set forth.

2. In combination with the above, the adjusting-lever E, operating so asto vary the elevation of the spindle L, substantially as set forth.
